4 Claims.

This invention relates to an apparatus for cleaning cesspools as used inand around canning factories and is preferably built into the cesspoolso that it is always installed and ready for immediate operation.

The general principle of the device comprises a circular top portion anda conical lower portion with a division wall about midway down into thecircular portion. The conical portion leads to an ordinary drain.

Located in the conical portion is an elevator driven from a suitablesource of power and adapted to collect the solid matter and convey itaway to some suitable place of disposal.

The division wall is provided with half its area perforated to dischargethe liquid portions of the accumulations in the cesspool and its otherhalf imperforate except for a large opening just over the elevator.

Arranged just above the division wall and moving in close relationthereto is a sweep arm for moving the accumulated material around overthe division wall to separate the liquid from the solids and have themdischarge in their proper channels.

It is therefore a principal object of the invention to provide acesspool cleaner that is power driven and permanently installed forimmediate operation.

It is a further object of the invention to provide a cesspool cleanerthat will be permanently installed and be provided with a division wallthat will separate the liquid from the solids.

It is also an object of the invention to provide a cesspool cleanerwherein there is a moving element to agitate the accumulations tofacilitate separation of the liquids from the solids.

It is also an object of the invention to provide a cesspool cleanerwherein an elevator is provided for accumulating the solids asdischarged from the cleaner and convey them to a suitable place ofdisposal.

With such objects in view as well as other ad vantages inherent in theinvention, consisting in the parts and combinations hereinafter setforth and claimed, it is understood that the several necprovements intheir applications to the particular construction chosen to illustratethe invention.

Referring now to the drawing, Fig. 1 is a plan of the apparatus.

Fig. 2 is a. vertical section somewhat offset from the center to showthe elevator in solid lines and the tank proper in central section.

Fig. 3 is a cross section of the elevator and housing therefor.` I

l represents the tank proper with the circular or cylindrical topportion and the conical lower portion.

2 is the division wall having the perforated section 3 and theimperforate section 4 with the opening 5 for the discharge of solids. 6is the sweep arm that travels over the top surface of the division wallto move the material around and agitate it so the liquids and solidswill separate readily.

'l is the elevator for receiving the solids that are passed through theopening 5, which may be of `any length desired or necessary to conveythe material to a suitable place of disposal, and is made up of suitablechains 8 with flights 9 moving through the housing 10.

The sweep arm and elevator are driven by means of the belt 11 comingfrom a suitable source of power and the mitre gears l2 and 13 and 14 and15 and short chain 16.

The liquid portion of the accumulations passes down through the conesection of the apparatus and passes through the opening 1'? to a drain.

The operation seems self evident without a special description. Materialis dumped promiscuously into the tank l and with the arm 6 sweepingacross the top surface of the division wall 2 the accumulations areagitated and stirred so that the liquid portions will pass through theperforations 3 and the solids will be swept through the opening 5, dropontov the elevator and be conveyed away. 95

What I claim as new and desire to secure'by Letters Patent is:

l. An apparatus for accumulating a mixed mass of material and separatingthe liquid from the solids comprising a tank, a division wall in saidtank one half of which is perforate and the other half is imperforateexcept for a discharge for solid material, means for agitating thematerial to better effect separation and means for accumulating thesolid material and removing it to a place of further disposal.

2. An apparatus for accumulating a mixed mass of material and liquid andseparating the liquid from the solids comprising a tank, a division wallarranged horizontally across said tank having a perforated portionadapted to pass liquid and an imperforate portion with a port adapted topass solids, a sweeper arm for moving the mass over said Wall soseparation can take place and separate means for receiving the solidsand liq uids and moving them away.

3. An apparatus for accumulating a mixed mass of material and separatingthe liquid from the solids comprising a tank, a division wall in saidtank and an open bottom in said tank, a portion of said division Wallbeing perforate for the passage of liquid and the other portion beingimperforate except for a discharge for the solid portion of said matter,means for agitating said mass of material to cause the liquid to passthrough said perforation and out of the bottom of said tank, a conveyorunder the discharge for the solid material to receive said material andconvey it to a place of disposal separate from the liquid.

4. An apparatus for Iaccumulating a mass of material and separating theliquid from the solids comprising a tank having an open bottom, adivision Wall in said tank a portion of which is perforate for thepassage of the liquid portion of said mass of material and the remainingportion of which is imperforate except for a discharge at one side ofthe center of said tank, means for agitating the mass to cause aseparation of the liquid which passes through the perforations and outthe bottom of the tank, a conveyor under the discharge for solidmaterial to receive material from said discharge and convey it to aplace of disposal separate from the liquid.
